structures and has for one of its objects to provide a' novel and improved sheet instal e railway box car rigid. Y

A further object is to provide an end wall which will be strong and construction made'u'p of' a plurality oisiieets having reinforcing ribs formed therein, the size ci' the sheet and form-or the 'ribs being so proportioned as'to perr'nit, the saine to be pressed in smaller presses having,` a niore limited .power than those for pressing larger sheets having the ordinary Atorni of reinforcing ribs.

A further object is to provide an improved construction for'anchoring or '-attachi-iig the ends of the reinforcing ribsto the corners of the car so as to increase the strength and rigidity of the endstructure. "The invention consists in the novel constructions, arrangements, and combina-tions to be hereinafter described and claiined Afor carrying out the above stated objects and suoli other objects fas will appear 'from the following description. l

This application is a division of my copending application Serial No. 338,075 filed November 14, 1919.

`I claim:

1. A sheet metal end panel for a railway carcomprising a metal sheet formed with a pressed rigidifying rib having an angle bar configuration at the middle and its ends bent over on diagonal lines to provide channeled portions which taper in depth' and which terminate with closed ends adjacent the sides et' the car.

2. A sheet metal end panel vfor a railway car comprising a metal sheet formed with a pressed rigidifying rib having an angle bar configuration for a portion of its length the res't being channeled, said panel provided with flanges at the ends thereof extending beyond the extremities of the rih for anchoring the ends of the panel to the car.

3. A. sheet metal end panel for a railway car comprising a metal sheet formed with an outpressed rigidiiying rib h-,zming its greatest depth adjacent. its middle and diminishing in depth toward its end and which has an angle bar configuration at the middle and is channel formed at its ends,` said ends being provided with anchoring flanges adaptedto loe attached to the sides of the car and the extremities of the channels being closed.

el. ln a'sheet metal end for a railway car, a metal sheet formed with side attaching flanges extending the entire height oi the sheet and adapted to be secured to the side of the 'car and -lso formed with an out.-
